Yep i got 18000 after the first tableau then 20400 after the second

I think y was 240 and z 120

Didn't like the last question, but never have liked those flow diagrams. How did everyone else do on it?


Does anybody know how the UMS marks tend to work out with D1?

Thanks

same... Max P was 20400.

y = 240
z=120 [i think]
x=0
r=0
s=0
t= something...

UMS is usually quite high for low percentages.. ie 70% = 80 UMS...

i dunno about the 77.. cant remember! [but i think i got that]

A and C depends on wat was the smallest distance.... i think the other 2 being G and E, had the smallest distance between them making the start/finish A/C

i definately put A as one to start/finish as tho!

Yay! Took this in Jan, and resat it today. Yeah, 98 for the flow, 20400 for the max profit. I think that paper went a lot better for me than the Jan one did... I was confident on all my answers apart from the definitions (which isnt maths, so im not bothered).

D1 is a lot easier the second time around..!!! Trust me!
